Sorry, but if you do VirtualPrivateNetworking, you dont have
to masquerade your ip's, cause they normally are private, not
internet routeable, but you even have to route, in case of freeswan
left and right subnet, to each other through the corresponding ipsec
device (freeswan does that automagically for you (eroutes)).
VPN gateways talk to each other with their public ip and the known
udp 500/prot50 mechanism.
